Expert writing Tips

Best practice

When using "is not", ensure the negation clearly applies to the intended subject and verb. Avoid ambiguity by placing the phrase correctly within the sentence.

Common error

Avoid placing "is not" in a way that unintentionally changes the meaning of the sentence. For example, instead of saying "He is not going because he is sick", consider "He is going because he is not sick" or "He is not going, because he is sick."
